That's good, probably just overfilled.  If it happens again when an experienced pro fills it I'd replace the fill valve.  The seal is just a rubber washer (or two) one way valve that flexes to let LP flow in and seals against outflow, and it can eventually leak.

There is no tube from the fill valve to the bleeder valve, at least not external to the tank.  mcneely
